Thank you for the info, I think I understand a bit more now. The stuff on Amazon says “Pueraria Mirifica (root) 1,000 mg (1 g) * (from 100 mg of 10:1 extract).” so I guess it’s not really potent enough to do much? I went to Ainterol’s site and had no issue with it working. But I noticed on their PM it says “Content: CO2 Pueraria Mirifica Extract Powder & 20 years grown Pueraria Mirifica root powder”. It also mentions the word extract, but it seems different on the numbers and percentages of what it is made from. I’m not sure I fully understand how it’s better, but if people have had good results with it then it must be better so I will order theirs vs the Amazon junk.
